Stretching type positioning felt cutting machine

Abstract

According to the stretching type positioning felt cutting machine, felt to be cut is placed on the table top of the workbench, and then the telescopic oil cylinder is controlled to drive the cutting machine head to move downwards till the bottom end of the stretching positioning plate makes contact with the upper surface of the felt. Along with continuous downward movement of the cutting machine head, the stretching positioning plate can move towards the two sides of the felt, and folds of the felt are flattened in the moving process. When the stretching positioning plate expands to the maximum angle relative to the cutting machine head, the stretching positioning plate can fix the felt to the table top of the workbench, and finally the felt is cut through the cutting knife. By the adoption of the structural design, the stretching positioning plate can be used for conducting flattening type positioning treatment on the felt, in this way, the felt can be positioned, the wrinkles of the felt can be flattened, and the felt cutting accuracy of the cutting machine is greatly improved.

Description

Technical Field

[0001] This application relates to the technical field of felt processing, and more specifically, to a stretching type positioning felt cutting machine. Background Art

[0002] Felt, a commonly used industrial tool, is mostly made of wool, and can also be made of cow hair or fibers, and is formed by processing and bonding. Its main characteristics are elasticity, and it can be used as materials for shock absorption, sealing, gaskets and the bottom felt of elastic wire card clothing. When in use, the felt needs to be cut according to the specific size specifications to avoid waste.

[0003] In the related art, traditional felt is mostly positioned by vertical extrusion during cutting. This method is very popular among industry insiders because of its simple positioning and low cost.

[0004] However, in the actual use process, when the felt is positioned by vertical extrusion, the felt is prone to wrinkling. This will not only affect the normal size of the cut felt, but also have a negative impact on the quality of the felt itself. Utility Model Content

[0005] In view of this, the embodiments of this application provide a stretching type positioning felt cutting machine to solve the problem that the existing felt cutting machine is prone to wrinkle the felt during positioning, thereby affecting subsequent cutting.

[0006] In order to achieve the above object, the embodiments of this application provide the following technical solutions:

[0007] A stretching type positioning felt cutting machine, comprising:

[0008] A workbench, which is placed on the ground through a frame;

[0009] An L-shaped column, which is connected to the frame and arranged beside the frame. The cross beam of the L-shaped column is located above the workbench, and a vertically downward telescopic oil cylinder is fixedly arranged on the lower surface of the cross beam;

[0010] A cutting head, which is fixedly arranged at the driving end of the telescopic oil cylinder, and a cutting knife is arranged at the bottom end of the cutting head;

[0011] Two stretching positioning plates, which are hinged at the two edges in the length direction of the cutting head. A torsion spring is also arranged between the two stretching positioning plates and the cutting head. In the non-loaded mode, the included angle between the stretching positioning plate and the bottom surface of the cutting head is an acute angle.

[0012] In some possible implementation manners, the length of the stretching positioning plate is greater than the distance between the cutting knife and the workbench.

[0013] In some possible implementation manners, a conveyor belt is arranged on the workbench.

[0014] In some possible implementation manners, a transfer plate is further included;

[0015] The transfer plate is arranged above the conveyor belt, and the to-be-cut felt is placed on the upper surface of the transfer plate.

[0016] In some possible implementation manners, strip-shaped holes are formed in the two sides of the transfer plate in the width direction along the thickness direction, walking rollers are arranged in the strip-shaped holes, and the transfer plate is connected to the conveyor belt through the walking rollers;

[0017] An L-shaped clamping plate is elastically and slidably connected in the strip-shaped hole. The horizontal plate of the L-shaped clamping plate is located on the upper surface of the transfer plate, and the vertical plate of the L-shaped clamping plate is located in the strip-shaped hole. The L-shaped clamping plate is used to move towards the walking roller and control its start and stop.

[0018] In some possible implementation manners, a pressing roller is arranged on the bottom surface of the stretching positioning plate.

[0019] The stretching type positioning felt cutting machine provided by the embodiment of the present application at least has the following beneficial effects:

[0020] In the stretching type positioning felt cutting machine provided by the embodiment of the present application, the felt to be cut is placed on the tabletop of the workbench, and then the telescopic oil cylinder is controlled to drive the cutting head to move downward until the bottom end of the stretching positioning plate contacts the upper surface of the felt. As the cutting head continues to move downward, the stretching positioning plate will move towards both sides of the felt and flatten the wrinkles of the felt during the movement. When the stretching positioning plate extends to the maximum angle relative to the cutting head, the stretching positioning plate can fix the felt on the tabletop of the workbench, and finally the felt can be cut by the cutting knife. By adopting the above structural design, the stretching positioning plate can be used to perform a flattening type positioning process on the felt, which can not only position the felt, but also flatten the wrinkled parts of the felt, thereby greatly improving the cutting accuracy of the cutting machine for the felt.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-3 shown, the stretching and positioning felt cutting machine provided by the embodiment of the present application includes a workbench 100, an L-shaped column 300, a cutting head 500, and a stretching and positioning plate 600. Among them, the workbench 100 is a tool and equipment for cutting felt, and the bottom end of the workbench 100 is placed on the ground through the frame 200. The L-shaped column 300 includes a vertical beam and a cross beam. The vertical beam of the L-shaped column 300 is fixedly connected to the frame 200, and the cross beam of the L-shaped column 300 is located above the tabletop of the workbench 100, and the cross beam of the L-shaped column 300 and the workbench 100 are parallel to each other.

[0029] The cutting head 500 is fixedly connected to the lower surface of the cross beam of the L-shaped column 300 through a telescopic oil cylinder 400. The telescopic oil cylinder 400 can control and drive the cutting head 500 to move up and down. A cutting knife 510 is provided at the bottom end of the cutting head 500. Therefore, when the driving end of the telescopic oil cylinder 400 moves downward, the cutting head 500 can cut the felt placed on the tabletop of the workbench 100 through the cutting knife 510.

[0030] The stretching positioning plate 600 is a structure for positioning the felt above the tabletop of the workbench 100. The two stretching positioning plates 600 are both hinged on both sides of the cutting head 500 in the length direction. Specifically, the stretching positioning plate 600 is connected to the cutting head 500 through a torsion spring, and a pressing roller 610 is provided on the bottom surface of the stretching positioning plate 600. Among them, in the non-loaded mode, the stretching positioning plate 600 extends outward in both directions, that is, the angle between the stretching positioning plate 600 and the bottom surface of the cutting head 500 is an acute angle. In addition, the length of the stretching positioning plate 600 is greater than the distance between the cutting knife 510 and the workbench 100, which ensures that when the telescopic oil cylinder 400 drives the cutting head 500 to move downward, the stretching positioning plate 600 can come into contact with the felt first to achieve positioning.

[0031] In the stretching type positioning felt cutting machine provided by the embodiment of the present application, the felt to be cut is placed on the tabletop of the workbench 100, and then the telescopic oil cylinder 400 is controlled to drive the cutting head 500 to move downward until the bottom end of the stretching positioning plate 600 contacts the upper surface of the felt. As the cutting head 500 continues to move downward, the stretching positioning plate 600 will move in the direction of both sides of the felt and flatten the wrinkles of the felt during the movement. When the stretching positioning plate 600 extends to the maximum angle relative to the cutting head 500, the stretching positioning plate 600 can fix the felt on the tabletop of the workbench 100, and finally the felt can be cut by the cutting knife 510. With the above structural design, the stretching positioning plate 600 can be used to perform a flattening type positioning process on the felt, which can not only position the felt, but also flatten the wrinkled parts of the felt, thus greatly improving the cutting accuracy of the cutting machine for the felt.

[0032] In some embodiments, a conveyor belt 700 may be provided on the workbench 100, a conveyor plate 800 is provided on the conveyor belt 700, and the felt to be cut is placed on the conveyor plate 800. Preferably, strip-shaped holes 810 are opened in the width direction on both sides of the conveyor plate 800 along the thickness direction, as Figure 2 and Figure 3 shown, walking rollers 900 are provided in the strip-shaped holes 810 of the conveyor plate 800, and the conveyor plate 800 is connected to the conveyor belt 700 through the walking rollers 900. A waist-shaped hole 830 is vertically provided beside the strip-shaped hole 810, and a telescopic spring 840 is provided in the waist-shaped hole 830. An L-shaped clamping plate 820 is slidably connected in the strip-shaped hole 810, and the L-shaped clamping plate 820 is connected to the telescopic spring 840. In the initial state, the L-shaped clamping plate 820 approaches the walking roller 900 under the action of the telescopic spring 840. At this time, the walking roller 900 will remain stationary, so the conveyor plate 800 can move on the conveyor belt 700.

[0033] When it is necessary to cut the felt on the conveyor plate 800, the stretching positioning plate 600 moves downward and contacts the upper surface of the conveyor plate 800. As the cutting head 500 gradually moves downward, the stretching positioning plate 600 will move towards the L-shaped clamping plate 820 until it contacts the L-shaped clamping plate 820 and pushes it away in the direction away from the walking roller 900. At this time, the walking roller 900 is in a rotating state, so the cutting head 500 can cut the felt on the conveyor plate 800.
